Abstract (en)

[origin: WO2010028340A1] Systems for protecting a wind turbine in high wind conditions are disclosed. A shrouded turbine may have an ejector shroud disposed adjacent and downstream of a turbine shroud. In one version, the ejector shroud can move to surround the turbine shroud. In another version, the turbine can be pivoted on a support tower to cover the intake end of the turbine and rotate the turbine about an axis at a right angle to the tower axis. In another version, the turbine is supported by a telescoping tower which may be retracted to lower the turbine in high winds. In another version, the tower sections may be connected by a pivotable connection and supported by guy wire(s) which may be lengthened to lower the upper tower section pivotally.
